Power Consumption

Power consumption was tested on the system as a whole with a wall meter connected to the OCZ 1250W power supply, while in a dual 7970 GPU configuration.  This power supply is Gold rated, and as I am in the UK on a 230-240 V supply, leads to ~75% efficiency > 50W, and 90%+ efficiency at 250W, which is suitable for both idle and multi-GPU loading.  This method of power reading allows us to compare the power management of the UEFI and the board to supply components with power under load, and includes typical PSU losses due to efficiency.  These are the real world values that consumers may expect from a typical system (minus the monitor) using this motherboard.

While this method for power measurement may not be ideal, and you feel these numbers are not representative due to the high wattage power supply being used (we use the same PSU to remain consistent over a series of reviews, and the fact that some boards on our test bed get tested with three or four high powered GPUs), the important point to take away is the relationship between the numbers.  These boards are all under the same conditions, and thus the differences between them should be easy to spot.

Power Consumption - 2x 7970 at Long Idle

No big shocks from the GIGABYTE in power consumption, falling in the batter half of the field and under 500W for our dual GPU gaming test.

Windows 7 POST Time

Different motherboards have different POST sequences before an operating system is initialized.  A lot of this is dependent on the board itself, and POST boot time is determined by the controllers on board (and the sequence of how those extras are organized).  As part of our testing, we are now going to look at the POST Boot Time - this is the time from pressing the ON button on the computer to when Windows 7 starts loading.  (We discount Windows loading as it is highly variable given Windows specific features.)  These results are subject to human error, so please allow +/- 1 second in these results.

POST (Power-On Self-Test) Time

POST time for the Z87X-OC is a little longer than I would have liked (ideally we prefer under 12 seconds).  I would have said that the additional USB 3.0 controllers might have been to blame, but the stripped boot option which disables these controllers only saved 2/3 of a second.  However the numbers do coincide with a fair number of other GIGABYTE boards, including the Z77X-UP7.

    Interesting motherboard. The OC emphasis and the included brace look to make it a pretty cool board for those wanting to up their OC efforts. Glad to hear it was reliable too, that is my primary consideration when purchasing a motherboard. :-)

    Motherboard seems to be very attractive and interesting looking forward to see the functions of it. http://www.koolchart.com

    Regarding the audio codec, I feel that anyone who could tell the difference between ALC892 and ALC898 or higher wouldn't be using onboard sound anyway.

    You obviously ignore the fact that there are college students with good hearing but restricted budgets. Of course those won't usually complain about the money save on the cheaper on-board sound either.

    Hello Ian and thank you for the review.

    Could you please tell us which BIOS version were you using for this review?
    I'm currently running under the official one (F6) that's posted on GIGABYTE's Website.

    Thanks again!
  • IanCutress - Friday, October 11, 2013 - link

    BIOS F6, as per the images on the BIOS section of the review: http://www.anandtech.com/Gallery/Album/3144#19
    I only ever use retail BIOSes downloadable from the website, and never 'BIOSes for review'. I want my results to be the ones you guys see.
    The only way I ever take beta BIOSes is usually if there's something that is fundamentally broken, or it's prelaunch and the relevant download pages are not available. Then I always ask for something as near to the public launch BIOS as possible.
    These reviews are always snapshots in time, as BIOSes in the future could have various performance tweaks or a shift in policy with regard idle states/MultiCore Turbo.

    Many thanks for the prompt and informative reply!

    Indeed I've seen the image but wasn't sure if that's what has been used for the actual review.

    Alright, time for some more OC tweaks here :)

    Regards,

    Heads up. The links for competing motherboards on the last page are mail links.
  • IanCutress - Friday, October 11, 2013 - link

    Thanks :) Fixed!

    This board is really compelling, I think the mix of OC features and mainstream price really speaks to enthusiasts (like us). It is a little sad that there is little reason to upgrade to an overclocked Haswell desktop from an overclocked Sandy or Ivy Bridge desktop because the Haswell chips just don't overclock as well so you end up with very similar performance after overclocking.

    I'm personally not seeing any reason to upgrade from my current i5-2500 @ 4.7Ghz. Hopefully Intel will release something more exciting sometime soon. Maybe whatever is after Broadwell, which doesn't look very interesting either.
